如何调试python flask应用程序到VS Code 2017

Question

I am working on the flask project. I am executing my project using

py app.py -v 

The app.py is the main file that runs the program. I have a backend.py where I call routes and methods. This is vs code settings

{

    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Flask",
            "type": "python",
            "request": "launch",
            "module": "flask",
            "env": {
                "FLASK_APP": "app.py"
            },
            "args": [
                "run",
                "--no-debugger",
                "--no-reload",
                "-v"
            ],
            "jinja": true
        }
    ]
}

I am also getting error due to passing -v as argument. Is that any specific way to pass the argument?

I want to debug backend.py method or route when user submit or perform any operation but my main application start by app.py . Please guide me, how I could do with vs code 2017.

You're passing -v to flask run , not to your own script. I suspect Flask has a way to flag when arguments to flask run stops and arguments to your own code starts (typically -- in other programs).
